Doesn’t it feel like vendors always update their certifications as soon as you get comfortable with them? Well, it’s happening again! Cisco has updated its main associate-level routing and switching certification, the Cisco Certified Network Associate (CCNA). But don’t fret; the content that’s getting a reboot only makes up about 25 percent of the test. […]

One of the biggest challenges for Cisco newbies working their way up the certification ladder is how to deal with learning the equipment and the Cisco systems without completely breaking the bank. Many people at the entry level simply don’t have a lot (if any) of money available to spend on an extensive CCNA lab. […]

One main capability of the AnyConnect client is that it provides a virtual private network (VPN) connection from a remote location to a second secured location.

Cisco has developed the AnyConnect Secure Mobility Client as a “next generation” Virtual Private Network (VPN) client. AnyConnect is not limited to providing VPN access; it has a number of other capabilities that enable an […]

One of the most (if not the most) important parts of a modern network is the hardware and software that is used to secure it. There was a time (many years ago) when devices on the Internet could be rather complacent with their security without worrying about the constant threat of attack; those days have […]

The wide scale implementation of IPv6 is ongoing and the pace is increasing steadily. With this implementation comes a whole new addressing structure to understand and support. As of the writing of this article, almost all major Internet carriers actively support IPv6. With this, the implementation of IPv6 on all major networks (public and private) […]

For those just getting into network routing protocols, it is hard enough to initially understand how all of them work.
